What is the best position for palatal implants? A CBCT study on bone volume in the growing maxilla
Clinical Oral Investigations, 2017Co-Authors: Darafsch Kawa, Martin Kunkel, Lothar Heuser, Britta A. JungAbstract:Objective The objectives of the present study are the following: (a) to investigate limitations (bone height, proximity to Nasopalatine Nerve and roots) in juvenile patients, (b) to review the recommended site for surgical insertion (level of the maxillary first premolars), and (c) to reassess the rationale behind the manufacturer’s age limitation (12 years). Patients and methods Cone beam CT images of 100 patients aged 10 to 20 years were analyzed. Vertical bone heights were measured in the median plane as well as 3- and 6-mm paramedian along the prospective axis of insertion, at the level of the first premolars (level 0), 3 mm anterior (level 1) and 3 mm posterior (level 2). The Mann-Whitney U test was used to compare bone heights between gender groups. Results The risk of damage to the Nasopalatine Nerve is highest in the median region on level 1 (46 %). The risk was lowest in the midsagittal region on level 0 (recommended insertion site; 3 %) and level 2 (0 %), as well as paramedian on levels 0 and 2. The risk of damaging roots was irrelevant for median insertion at all levels; the only critical region was 6-mm paramedian on level 1. Conclusions The recommendation of surgical insertion at the level of the maxillary first premolars is still justified, but a slightly more posterior implant position might improve safety. We found no relevant growth-related changes in the vertical bone heights in the median palatal area. Thus, our data do not support the strict 12-year age restriction for palatal implants.

displacement of the incisive foramen in conjunction with implant placement in the anterior maxilla without jeopardizing vitality of Nasopalatine Nerve and vessels a novel surgical approach
Clinical Oral Implants Research, 2000Co-Authors: Zvi Artzi, Carlos E Nemcovsky, Ilan Bitlitum, Pnina SegalAbstract:Accurate implant placement in the anterior maxilla is essential in achieving optimal prosthetic rehabilitation with proper function and acceptable esthetic and phonetic demands. One of the preferable prosthetic solutions to restore a missing maxillary incisor in young adults is by an implant-supported crown. Bone resorption together with an enlarged incisive foramen, challenge proper implant placement. A simultaneous procedure where the implant osteotomy site penetrated the incisive canal is presented. A configurated cortico-cancellous block graft core was adjusted to fit the foramen while its soft tissue content was pushed back posteriorly but not removed. This procedure was followed by an immediate implant placement. Re-entry at 9 months revealed solid bone support embracing the implant body. Although the size of the incisive foramen diminished significantly, the Nasopalatine branches were still evident. No complications and/or loss of sensation were observed.

Anaesthetic efficacy of a labial infiltration method on the Nasopalatine Nerve
British Dental Journal, 2008Co-Authors: E. Lassemi, Mohammad Hosein Kalantar Motamedi, S. M. Jafari, K. T. Talesh, F. NaviAbstract:Background and aim The conventional Nasopalatine Nerve block is commonly used to obtain anaesthesia in the anterior portion of the palate. The painful nature of this approach, however, has led investigators to seek alternative methods to obtain anaesthesia. Labial infiltration of the maxillary central incisors can be considered an effective anaesthetic approach for the anterior palate. Our study aimed to assess the anaesthetic effect of a modified labial infiltration method on the Nasopalatine Nerve. Materials and method A case-control clinical trial was done on 60 patients referring for extraction of maxillary incisors (mean age 44 years). The patients were divided into two groups of 30 people. For the first group, a primary conventional infiltration was given to each patient from a point between the maxillary canine and the lateral to obtain preliminary anaesthesia for the maxillary anterior labial area. The second or the control group was anaesthetised by conventional injection into incisive papilla. Two to three minutes afterwards, a labial infiltration approach was done and the amount of pain determined by OPS (objective pain score) was assessed. After five to six minutes the level of anaesthesia in the anterior palate was assessed in both groups by an explorer and recorded as pain-free, mild pain or severe pain. The sign test was used to statistically analyse the data (p

Anaesthetic efficacy of a labial infiltration method on the Nasopalatine Nerve
British Dental Journal, 2008Co-Authors: E. Lassemi, Mohammad Hosein Kalantar Motamedi, S. M. Jafari, K. T. Talesh, F. NaviAbstract:This technique makes anaesthesia of the anterior palatal area less painful for the patient. The technique of anaesthetising the anterior hard palate will be more easy for dental students to learn. The injection site is more accessible and the risk of injection necrosis of the palatal mucosa is omitted.

The sign test was used to statistically analyse the data (p <0.001). Results Total, moderate and no anaesthesia were observed in 76.7%, 13.3%, and 10% of the patients receiving anesthetic injection at the labial side. For the control group, these results were 83%, 17% and 0% respectively. Conclusion This method of labial infiltration may be an effective alternative to the painful conventional palatine Nerve block to obtain efficient anaesthesia of the anterior palate (p <0.001).
